Preheat oven to 400 degrees. Cut the chicken into bite size pieces

Spread panko in a thin layer on rimmed baking sheet and bake for 5 minutes, until golden brown.

Transfer the panko to a shallow dish and mix in the Parmesan and coarse salt. Drizzle the oil and mix well. Set out the flour and eggs in separate dishes.

Increase the oven temperature to 450°F. Place a wire rack on the baking sheet, spray lightly with cooking spray.

Working in small batches, coat the chicken in flour, shaking off any excess, dip in egg, and then coat well with panko. Transfer to the rack. Bake the chicken 12-15 minutes, turning over halfway through.
